If you read the online fishing forums you will have heard of Mighty Bright Reflective Tape. Don't be fooled by the black colour of Eclipse, this highly reflective tape is ideal for adding to rod tips to enhance bite detection at night but can also be used in small strips on bait knives etc making them easier to pick out in the dark. It reflects the light from any source and glows silver/white making your rod tips highly visible in the dark.
